A device and method for drying poria cocos with temperature control and humidity control

Abstract

The invention belongs to the technical field of processing of agricultural products and relates to a device and a method for drying poria cocos by controlling temperature and controlling humidity. The device for drying poria cocos by controlling the temperature and controlling the humidity is mainly used for drying and processing the poria cocos. The device comprises a drying box (1), a hot air circulating unit, a hot air humidifying unit, a water supplying unit and a control unit, wherein the hot air circulating unit, the hot air humidifying unit, the water supplying unit and the control unit are coupled on the drying box (1) so that the temprature, humidity and air speed of circulating hot air in a drying chamber (31) can be effectively controlled. The device and the method have high efficiency and are convenient to use; the temprature and humidity can be effectively adjusted when the poria cocos is dried; the drying speed is fast and obtained poria cocos dices have a large compacting degree, are not easy to damage and have white texture; the condition is better, the defective rate is low and the loss of nutrients is less; the later storage, transportation and processing are easy to realize, and water conservation, energy conservation and environment protection are realized; automatic control can be realized.

Description

technical field [0001] The invention belongs to the technical processing field of agricultural products, and relates to a device and method for drying poria cocos with temperature and humidity control. Background technique [0002] Poria cocos is the sclerotium of polypore fungi, and its "dual-use for medicine and food" makes it very much in demand. In the processing of Poria cocos, drying is the most critical step, generally based on the traditional hot air drying process. Compared with other seasonal agricultural products in the same period, Poria cocos has a lower water content (about 50%) and higher starch content. During the hot air drying process, it is easy to cause uneven moisture inside and outside the poria cocos, concentration of stress on the surface of the poria cocos, and even lead to The "burst" of Poria cocos directly affects the quality and appearance of the product. In order to solve this problem, the existing manufacturers and farmers adopt the "intermit...

Problems solved by technology

This will adversely affect the medicinal effect of Poria cocos, also can make medicine produce peculiar smell, reduces the commercial value of Poria cocos

[0004] For the processing of Poria cocos, the research mainly focuses on the application of active ingredient extracts and the processing of subsidiary products; for example, the application number is 201410317257X, a kind of ultrafine wall-broken Poria cocos powder composition and its preparation method; another example is the application number 2014102924659 is a Poria cocos biscuit and its preparation method; another example is a Poria cocos dicing machine with application number 2014100165409, which can quickly cut Poria cocos into cubes; but none of them involve the drying process of Poria cocos
